Lately I find that after a couple of days use - about when the reed is broken in - after I've played for a while the reed starts to shut off the airflow, as if it suddenly weakened. When I remove them, the reeds are warped, bent, or curved (?) toward the mpc. This happens on different horns, with different reeds so it's got to be me. I don't think I'm biting but must be using too much pressure, for some reason. So- should I try to get a softer embouchure (not sure how to do this since I don't know what I'm doing differently) or goto a harder reed to resist the bending (I really find harder reeds difficult to play for long) or go to a softer reed ( maybe this will make me use less pressure). I usually use 2 1/2 or 3 vandoren's on tenor and alto. I'd be grateful for any suggestions.
